Fig. 27 is a vertical cross section on line 2727 of Fig. 2; Fi 28 is a detail elevation of the soldering mec anism,and Fig. 29 is a section on line 2929 of Fig. 28.

The can body making machine embodying my invention, and shown in said drawing,

comprises in cooperative combination a can body blank feeder for automatically feeding the blanks one by one from the stack or pile, a blank conveyer, two pair'of clamps, one clamp of each pair being provided with an edge folding or book forming lip, a pair of rotary or rocking hook I formers. or edge folders operating in conjunction with said clamps to form the reversely or edge folds on the opposlte ends of the blank by the downward and upward rocking movements of said rotary or rocking hook formers, an expansible or collapsible body" former horn having an upward and downward movement to permit the blank to be conveyed under the horn, a stationary or rigid anvil or support for the up and down movable and expansible horn, a reciprocating bumper for closing the interlocked hooks or edge folds into a seam against the horn, a wedge or cam carried by the reciprocating bumper or its slide for operating or expanding the horn, a pair of wings or folders for bending or forming the blank around the horn, a soldering horn connected to the end of the body former horn, a flux or acid applyingdevice for fluxing the seam, a soldering iron cooperating with the soldering horn to solder the side seam of the can body as it is moved along between the soldering iron below and the soldering horn above, a wire solder feed device and mechanism for operating or controlling the operation of the same by the movement of the can body along turned. hooks the horn so that the solder will be fed'if a can body is present to receive the solder, but not fed if no can body is so present, and mechanism for moving the can body from the body former horn along the soldering horn and discharging the same from the machine, and means for operating or imparting to the several cooperative moving devices or parts of the machine their required movements.

My invention also consists in the novel construction of parts and devices and in'the novel combinations of parts and devices herein shown or described, and more particularly specified in the claims.

In the drawing, A represents the frame of the machine. 7

B represents the blank feeder or device for feeding the flat can body blanks a: one by one automatically from the stack or pile X of blanks in the holder B of the feeder.

C is the blank conveyer by means of which the rotary or rocking edge folders or hookformers E form the oppositely turned edge folds or hooks m m on the opposite ends of the blank :2. The lower clamp D of each pair is mounted on the stationary frame of the machine, and the upper clamp D of each pair is preferably the movable member and is adapted to be moved or pressed downward so as to properly clamp the can body blank. Each movable clam D is preferably secured to a movable bar D having arms or lugs d pivotally connected at d to the stationary frame ofthe machine so as to admit of the necessary slight movement being imparted to the movable clamp. One clamp of each pair is provided with a hook forming lip d over which the hook or edge fold is formed or bent, the hook forming lip d being on the upper clamp D to form the upturned hook 40 and on the lower clamp D at the opposite end-to form the downturned hook or edge fold a. Each of the two rotary or rocking hookformers or edge folders E is secured to a rocking holder E by or through which the necessary rotary or rocking movement is imparted to it. The two rocking hook formers E are alike and are reversely mounted or disposed so that one will form an upturned hook and the other a downturned hook. Each of these rockin hook formers is furnished with a" longitudinal recess or roove e to receive the projecting end of t e blank :22,

and serve as a guide therefor in adjusting the position of the blank between the two hook formers. Each of the hook formers E is also provided with a projecting shoulder or head 6 which engages the projecting end of theblankand bends it at rightangles to the plane of the blank, as illustrated, for example, in Fig. 8, when the hook former is rocked in one direction, and also with a shoulder or bead e and projecting lip e which serve, when the hook former is rocked in the opposite direction, to complete the formation of the hook m or av over the forming lip d of the clamp D or D. After the formation of the hook 1s thus completed, the hook former E returns to its central or normal position.

. The upper or movable-clamps D rest normally with their own weight and with that of their bars orholders D on the blanks a: as they are fed or conveyed forward beneath the same by the blank conveyer C, and serve not only to straighten, smooth and flatten the blanks, but also to prevent danger of the blanks being overcarried by the conveyer in its quick or rapid reciprocating movement, thus insuring the blanks beingalways properly presented to the edge folders and to the horn. The upper" or movable clamps D D are given their necessary slight downward movement to cause them to firmly grip the blanks against the lower clamps D D by means of a movable presser foot D which is furnished with adjusting screws D to engage the clamp bars or holders D To further insure the blanks on being maintained in a straight flat position, the presser foot D is provided with a clamp bar D which engages the blank at its middle, and which is furnished with a spring D to force the same yieldingly against the blank. The guide a on the frame of the machine opposes the spring clamp bar D The blank conveyer or carrier C is provided with two pair of pawls 0 so that at each movement-of this conveyer one blank is moved forward to the hook formers E E, and the next receding blank is moved forward from the ormers E to the horn F and the anvil block or support G. The body former horn F is expansible and collapsible or provided with movable segments or wings f hinged to the main portion of the horn, and adapted to be expanded after the hooks or edge folds m m are carried past each other, as illustrated in Fig. 19, so as to interlock or draw the hooks together, as illustrated in Fig. 20, before the seam is bumped, as illustrated in Fig. 21. The win or clamps f f of the horn are thus expande or spread apart by means of a wedge f mounted to reciprocate in the main portion of the horn, and which engage wedge blocks 7" f on arms f hinged to the horn at f, and which bear against adjusting screws f on the movable wings or segments f of the I closing the seam.

' are segmental in form and conform to the horn. A spring f returns the wedge to poimpart a yielding f-movement to the body sition, and flat springs 'f serve to retract the wings of the horn. The wedge f is provided with an inclined face .7" so that it may be operated by a wedge finger or projection f carried by the bumper K by which the interlocked hooks or edge folds m m are compressed together and into the longitudinal groove f in the upper side of the horn, thus forming the lock seam m which is thus caused to project on the inner surface of the can body X The horn F is an up and down movable horn, the same having a slight upward movementto liftitslightly off the anvil or block G in order to permit the can body blank a; to be fed or slipped under the horn and between it and the anvil'or support G upon which the horn normally rests, and which firmly supports it against the thrust 'or blow of the bumping hammer K in bumping or This slight up and down movement of the horn also causes the blank m to be firmly clamped at its middle portion between the anvil or block Gr and the horn while the blank is being folded or formed around the horn by the can body folders or formers H H, thus insuringthe proper registry of the two ends of the blank and the hooks or edge folds thereon together, and

preventing the can body being formed irregularly or askew,-and insuring regularity,

uniformity and perfection in the formed can bodies, while permitting the work to be done very rapidly. T 0 give the necessary slight up and down movement to the horn F, I mount it on a bent lever F pivoted to the frame at F and operated by a cam m on the cam shaft M. 1

The'body formers, folders or wings H H surface ofthe horn, each being somewhat less than a semi-circle in extent. Each of these body former wings or folders H is provided with a hinged arm h by which it is hinged at h to the anvil block G or other stationary portion of the machine. These winged folders H are opened and closed around the horn by means of a vibrating lever H pivoted to the frame at H and connected by pivoted links H to arms or lugs H on the body former wings or folders H; Each of the links H is furnished with an adjustable member H and an adjusting scren or turn buckle H to properly adjust the movement of the body former wings or folders H; These links are so adjusted that one of the wings or folders H closes slightly before the other, so as to cause the outer hook or edge fold a1 to overlap the inner hook or edge fold m The lever H is operated by a cam m on the cam shaft M through a connecting link H which is furnished with a spring H and an adjustable nut H so as to the inside of the can.

' former wings orfolders H. e

' The bumper K 1S given an up and down reclprocatlng movement to cause the same to bump or compress the folds of the seam together through a reciprocating, slide or cross head K operated by an eccentric M on the cam shaft M through the connecting link K After the seam has been bumped, the can body is discharged from the can body former horn F and pushed on to the soldering horn N, the end of which is connected directly to the end of the body former horn, by means of a third pair of can body discharge fingers orpawls c 0. on the reciproeating can body blank conveyer C. The soldering horn N is preferably of skeleton seam and. through the foldsthereof without unnecessarily smearing the surface of the can body adjacent to the seam with solder either on the outside or on the inside of the can body. The soldering iron P is preferably about a foot or more in length so as to give the requisite rubbing or sweating action against the outside of the seam as the can body is moved along by the soldering conveyer U under the solderlng iron.

S is the aciding or fluxing device by which the acid or other flux is applied to the lock side seam of the can body before it passes along the soldering iron. This fiuxing device S preferably consists of a rubbing device of absorbent material, secured to a holder or bar S pivotally connected to an arm S which is hinged to the frame at S The acid or flux is contained in a tank S and is fed'drop by drop upon the fluxing device throu h a pipe or nozzle S which is furnished wlth an adjusting valve S to regulate the fiow.

The soldering iron or shoe P is preferably furnished near its front end with a solder cup, cavity or hopper "p, having a small opening atits bottom through which the molten solder may flow onto the seam of the can as it passes underneath the soldering v iron. The; groove n in the soldering horn beneath the seam catches or collects any solder which may sweat through the seam onto T are the heaters preferably gas burners for projectin flame against the soldering iron and so dering &

horn, and for melting and keeping melted the solder and'heating the seam during the soldering operation. The soldering iron is preferably furnished with a flameconfining chamber or shell P partially surrounding the same for directing and confining the flame of the gas burners or heaters against the soldering iron. The soldering iron and its flame confining chamber are preferably furnished with a heat confining jacket P The soldering iron may preferably be connected to the shells P P which thusserve as a frame or mounting for the soldering iron. The soldering iron and its shells or chambers preferably rest with their own wei ht directly upon the cans or the seams of t e cans as they are moved along under the soldering iron. When no can bodies are under the soldering iron, the soldering iron may'rest or be supported on the soldering horn itself. Stationary guides P surrounding the soldering horn or its connected shells confine the same in position on the soldering horn,

U is a continuously moving can bodyconveyer for moving the can bodies along the soldering horn, first under the fluxing device S, and then under the soldering horn and for finally discharging the can bodies from the machine over the end of thesoldering horn. This continuously moving can body conveyer U preferably consists of a pair of endless chains furnished with can body pusher arms or fingers U and traveling upon pulleys or sprocket wheels U on the upright shafts U U The outer end of the soldering horn rests upon a revolving pulley or rotary support V so as to permit the can bodies to be readily discharged from the free end of the soldering horn. The soldering horn supporting pulley or wheel V is preferably positively driven, and this I refer to do by means of a chain V and driving pulley V on the shaft M, pulley V on longitudinal shaft V having bevel gears V meshing with bevel gears V on the transverse shaft V. furnished with bevel gears V which mesh with bevel gearsV on the driving shaft U of the can body conveyer chains U, thus communicating motion to the soldering conveyer U. 4

W is the spool or reel for the wire solder w which is fed to the machine by a pair of wire solder feed wheels W the shaft "W of one of which is furnished with a ratchet wheel W. actuated by a pawl W on a pawl lever W pivoted at W to the frame of the machine. This pawl lever W is operated or vibrated as required to feed forward the requisite length of wire solder for soldering each can by means of a link W having a roller 'W which engages a cam W on the shaft V The vibrating pawl lever W also carries a knife W which, cooperating with The shaft V is the solder wire guide W cuts ofl the required amount of solder from the solder wire for soldering each can at each stroke of the pawl lever, so that the cut length m of solder may drop through the guide or tube 7 into the solder cup or funnel p on or in advance of the soldering iron P where it is melted by the heat of the soldering iron or-of the flame projected against the same, and caused to fall down upon the lock side seam w of the can body X. To prevent the forward feed of the solder wire except when a can body is being advanced along the soldering horn ready to receive the solder, I provide a wire solder feed trip device Y which is operated by engagement with the can body itself as it is advanced along the soldering horn, so that the operation of the wire solder feed is controlled by the can body itself, thus causing no solder wire feed to take place unless there is a can body present on the soldering horn to receive the solder thus fed for it. This wire solder feed trip device Y preferably consists of a movable shoe, normally resting in the groove n of the soldering horn, and adapted to be rested or lifted up by the passage of the can body under it along the soldering horn, and through which by suitable connecting mechanism, motion is communicated to the pawl N on the pawl lever l/V and therebymoves the pawl into position for engagement with the ratchet wheel W of the solder wire feed roller, and thus causes the ratchet wheel of the solder wire feed roller only to be turned by the stroke of the pawl lever \V when the trip device Y has been operated by engagement with an advancing can body. The solder wire feed trip device Y has an operating lever Y connected by a link Y with a lever Y which engages a pin V on the pawl /V, this being a convenient connecting mechanism for communicating motion from the trip device Y to the'p'awl lever. The pawl lever TV has a slot WV for connection with its cam operated link W so that the stroke of the pawl lever and the consequent feed of the solder wire may be adjusted or regulated as desired. This enables the machine to adjust the solder wire feed to the sizeor length of the can bodies being soldered, as varying amounts of solder are necessary for difierent kinds of work or different kinds of cans.

Z is a wiper for removing surplus solder from the outside of the seam, the same being preferably mounted on a lever Z furnished with a spring Z for compressing the wiper against the can bodies as they are moved along the soldering horn.

Z is a seam cooling device to cool the freshly soldered seam, and cause the solder therein to quickly set. .This cooling device preferably consists of a compressed air pipe, furnished with a series of nozzles or openv against theseam.

'Z are supply pipes for supplying compressed air to the seam cooling device and T are gas supply pipes and T air supply pipes for supplying gas and air'to the heaters or burners T by which the soldering horn, soldering iron and seams of the cans are heated as required for soldering the seams.

The can body blank feeder B and its blank holder B are preferably constructed substantially as shown and described in. the Leavitt & Hodgson Patent No. 522,261 of July 3, 1894, that is to say, the feeder B has a shoulder b which projects from'the inner face of the feeder about the thickness of one of the blanks w so as to engagethe lowermost blank only of the pile and shift or slip it upward intothe slot of the feeder safe guard or separator B of the feeder, and thus disengage the blank from the lip b of the holder blank B The feeder B itselfhas two movements, one a sliding or reciprocating movement to'slipthe disengaged blank into the slot 6 of the separator B and disengage the lower edge of the blank from the lip b of the holder B and the other movement being-a swingingor lateral one to permit the blank to drop down upon the blank conveyer orcarrier C. To provide for this double movement of the feeder B, it is mounted to slide in a pivoted or swinging guide B The required sliding or reciprocating movement is imparted to the feeder by a cam B, on shaft M connectin link B, levers B and B and connecting ink B The required pivotal or swinging movement is communicated to the feeder B or its guideB by means of an arm B rock shaft B link B, and cam B on shaft M B is an extractor which serves to push the blank 50 out of the slot 6 of the separator B in case the blank should tend to stick therein.

As the blanks are fed or delivered one by one from theholder B by the feeder B, they a fall upon or over the reciprocating conveyer or carrier bar C, by which the blanks are conveyed or carried forward to the edge folding or hook forming devices E and clamps D. The presser foot D by which the upper or movable clamps D D are caused to firmly clamp the blank against the lower clamps D D is operated by a cam m on the cam I shaft M, the presser foot operating arm or slide D having a spring D to move it in the opposite direction. The can body blank conveyer C is reciprocated as required to feed the blanks forward, first to the edge folders or hook formers E and then to the horn by means of a link C lever C link C and crank G on the shaft M The edge folders: or hmok fm'mers E are rocked as required to form the hooks or edge folds by means of arms or levers E on the hook formers E, connecting bar E reciprocating in guides E, link E- connected to a lever B", pivoted to the frame at E and having .a roller E engaging the cam E onthe shaft M". After leaving the end of the soldering horn the can bodies are delivered upon a discharge conveyer V preferably consisting of a pair of endless belts, traveling on the pulleys V and V, and by which the can bodies are discharged from the machine. The transverse shaft V has a hand wheel V soldering conveyers U to be moved by hand and the can bodies in the machine discharged by hand in case the machine becomes accidentally stopped or clogged.
